Contractors involved in bridge deck resurfacing should be aware of this potential issue:
The contractor R.E. Pierson of Bridgton, N.J. hit a snag after the bridge deck was milled to remove the asphalt road surface and left 3/8” of residual asphaltic Tar Tack Coat on the concrete deck. The contractor spent several frustrating weeks scraping the surface with an excavator and skid steer trying to remove the asphaltic material. Since the deck was going to receive a waterproofing membrane, 100% of this asphaltic material had to be removed leaving the contractor in a bind. After much discussion Kenseal a supplier referred ShotBlast, Inc. to solve the problem.
ShotBlast, Inc has a full arsenal of concrete milling, grinding and shotblasting equipment. The problem was attacked with specialized diesel powered dust free scarifying equipment to totally remove the asphaltic material and leave a clean profiled concrete deck ready for the waterproofing membrane. Mike Capasso from R.E. Pierson was happy with the speed and professionalism of ShotBlast’s service. The bridge resurfacing schedule could resume without delay.
Southeastern Pennsylvania Transportation Authority (SEPTA) is currently in the process of expanding their fleet by adding new locomotives and multi-level cars. In order to accommodate these new vehicles, their Frazer Shop will be undergoing significant renovations.
This is a multi-phase project.
Phase 1: Earthwork and stormwater improvements
Later Phases: Construction of additional shop building and vehicle maintenance equipment, additional track modifications, and a new vehicle washer
Shot Blast Inc. was lucky enough to participate in this process. Check out the photos below for an inside look at the team preparing the concrete for an epoxy coating.
This project started in the spring of 2016 and should wrap up in the fall of 2019.
Recently, we took on a project in Philadelphia at NBC 10’s studio. In the photos, you can see our team in action removing the existing, worn tile floor and grinding the concrete underneath.
Next, we applied an epoxy coating and sealed the flooring with a coat of urethane. This new flooring is sleek and will last for years to come.
Day 1: Removing the existing tile and mastic and grinding the concrete.
Day 2: After applying an epoxy coating and before sealing with urethane.
We had the opportunity to help one of our clients, Collegium Charter School in Exton, PA, with their new gymnasium floor.
We removed the tile from the 6,400 sq ft surface and blasted the concrete underneath.
For safety reasons, when installing a floor in a gym, it is crucial that the surface is free of any cracks and that it is smooth. This will significantly reduce the risk of tripping and falling.

Back in September, we traveled to Fredericksburg, VA to take on a project for a customer. We performed a blast and seal on a 220,000 sq ft surface.

The bridge over the Christina River in Wilmington is having some work done to it. In order for the contractor to be able to apply new coatings to the bridge it first has to be prepared.
This week we shot blasted 425,000 square feet on the north bound side of 495.
